Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the potential impact of introducing zonal electricity pricing on (a) consumer energy bills in regions with high renewable generation, such as those with significant offshore wind capacity, (b) the cost to the public purse of constraint payments to wind generators and (c) future private-sector investment in energy infrastructure in areas of high demand, including the South East.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
In July 2025, we announced that we would not be implementing zonal pricing as part of the Review of Electricity Market Arrangements (REMA) and had decided instead to retain a single Great Britain wide wholesale electricity market. We plan to set out the potential impact of zonal pricing − with respect to areas such as consumers, generators and investment, including South East England – in the REMA Cost Benefit Analysis (CBA), which will be published later this year.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, how often gas-fired power stations were used to replace curtailed renewable generation in 2025.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
The Department does not hold the requested information. It is owned by NESO and published on the Elexon data portal.
Asked by: Perran Moon (Labour - Camborne and Redruth)
Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, how much funding within the consolidated low income household energy efficiency scheme will be ringfenced for community level low carbon heat technologies, including (a) Shared Ground Loops and (b) heat networks.
Answered by Martin McCluskey - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)
The Government’s Warm Homes Plan includes £5 billion targeted investment for home upgrades for low-income and fuel poor households. As part of this offer, from 2027/28 the Government intends to integrate the Warm Homes: Social Housing Fund and Warm Homes: Local Grant into a single low-income capital scheme, which will shift toward area-based delivery. The Government will say more about the evolution of our low-income schemes this Spring, including the scope of funded technologies.
In addition to any forthcoming funding from these schemes the Government is investing £1.1bn in low-carbon heat networks over this Parliament, and accelerating their rollout through Heat Network Zoning. We have also taken action to strengthen consumer protection through appointing Ofgem as the Heat Network regulator.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of whether curtailment payments create incentives to locate generation in areas with insufficient grid capacity.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
The revenue that generators can make from curtailment payments is regulated by Ofgem through the Transmission Constraint Licence Condition. This regulation limits the revenue generators can make from being curtailed to the value of the revenue lost through not being able to generate plus reasonable costs. Ofgem can and does take enforcement action against generators that it believes are not complying with this regulation.
The Strategic Spatial Energy Plan (SSEP) will optimise the siting of new sources of electricity generation across Great Britain. The Government’s Reformed National Pricing programme will have the SSEP at its heart, and reforms will be designed to ensure incentives for generation projects encourage siting and investment in areas that align with the SSEP.

Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what estimate his Department has made of curtailment costs to electricity billpayers in 2026.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
Data on the aggregate impact of curtailment payments to electricity billpayers is calculated by the National Energy System Operator (NESO) and can be found in NESO Annual Balancing Report, the next of which will be published later this year. The most recent NESO Annual Balancing Report was published in June 2025, covering the 2024/25 financial year, and can be found via this link: neso.energy/document/362561/download
Asked by: James McMurdock (Independent - South Basildon and East Thurrock)
Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what the expected completion dates are for major new transmission projects intended to reduce renewable curtailment.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
The Clean Power Advice to Government, published by the National Energy System Operator in 2024 set out the list of over 80 transmission projects needed to meet Clean Power 2030, and their required delivery dates. These projects will alleviate curtailment and allow more renewable power to serve homes and businesses across the country. Updates on the expected completion dates of these projects is a matter for the Transmission Owners which design, run and build the high voltage network.
Asked by: James McMurdock (Independent - South Basildon and East Thurrock)
Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what measures are in place to limit curtailment costs during the period before new grid infrastructure becomes operational.
Answered by Michael Shanks - Minister of State (Department for Energy Security and Net Zero)
The Government, the National Energy System Operator (NESO) and the Office of Gas and Electricity Markets (Ofgem) are pursuing measures which will reduce constraint costs in the short term. These include making best use of the existing network, deploying smart grid technologies and taking measures to reduce the amount of time networks need to be out of service for essential new build and maintenance. NESO is also progressing other technical measures at pace via the Constraints Collaboration Project. We intend to announce further measures in the Reformed National Pricing (RNP) Deliver Plan which will be published shortly.
